Hi,
first of all, since this is my first message here, I must thank you  
all for providing invaluable content to be lurked by me in the past  
months :-)
Second, I apologize for my bad English.

I think I have a similar problem in my 35/2 R, late model.
In difficult situations, it is very flare prone, and a very strange  
one. Sometime ray of light are "curved", sometime are similar to a  
rainbow.
It is also very sensible to ghost with sun on field or near the  
border of image, and it shows very noticeable red ghosts.

This is true with both film (on a R6.2) and digital (on a Canon 5D).

The serial number is 326xxx, do you think this is normal for this  
lens, and younger ones are better coated or something, or I should  
send my lens to Solms for checking/cleaning, etc.?
I think so because I have other lenses, even wider, that perform  
much, much, better in similar situations.

Here are some example, some very bad picture that however show the  
problem.
All three taken with 5D, unretouched, just RAW converted (I repeat,  
though, that with film is the same. Just don'have a scanner :) )
Sea ones at f8 and night one more open. All three with hood extended.
